The invention discloses a converter device of a symmetrical structure. The converter device of the symmetrical structure comprises two input power sources V1 and V2, an input capacitor C1, an output capacitor C2, two energy storage inductors L1 and L2 and three switching tubes, wherein an adjusting voltage Uc is generated across the two ends of the input capacitor C1, and an output voltage Vo is generated across the two ends of the output capacitor C2. According to a direct-current converter, due to switch-on and switch-off of the first switching tube, the second switching tube and the third switching tube, the adjusting voltage Uc generated on the input capacitor C1, and the combined action between the adjusting voltage Uc and an input current I1 generated by the input power source V1 as well as between the adjusting voltage Uc and an input current I2 generated by the input power source V2, an output current IC is generated to the output capacitor C2, and the magnitude of the output current IC can be increased or decreased through combination between different switching tubes. The input current and the output voltage of the direct-current converter are small in ripple, the service life of the input power sources can be easily prolonged, the device is simple in structure, small in number of required switching devices, low in loss and high in efficiency, performance of the converter can be effectively improved, cost can be reduced, and the output current is controllable.
Description
technical field [0001] The invention relates to a converter, especially a DC converter with a symmetrical structure. Background technique [0002] In recent years, energy shortage and environmental pollution have become the focus of the world, and the development and application of renewable energy have attracted widespread attention from all over the world. In the renewable energy power generation system, the electric energy generated by many renewable energy sources is low-voltage direct current, and high-voltage direct current is required for power transmission to the grid, so a DC-DC converter is required to convert the low-voltage direct current into suitable and high voltage direct current from the network. In the field of clean energy electric vehicles, it is often necessary to convert the low-voltage single direct current provided by the battery into high-voltage direct current of different voltage values, which has high requirements on the efficiency of DC-DC conve...
